How to use Yii2 Sluggable Behavior without showing id number? - php

Question

I have read the question on using SluggableBehavior in Yii2
and in my trial case I can generate url like article/1/First-Article using the rule in urlManager
'article/<id:\d+>/<slug>' => 'article/view',
and using
\yii\helpers\Url::to(['article/view', 'id'=>$model->id, 'slug'=>$model->slug])
to create url.
In my real case, I use ['article/view', 'hash'=> $model->hash, 'slug'=>$model->slug] to generate url. My rule is
'article/<hash:[\d-\w]+>/<slug>'=>'article/view'
My url is like article/1e482d69129d760e9494b2c6e86eba2b/First-Article.
I want to only show url like article/First-Article, i.e. not showing the hash code in the url. Is there a way to achieve this? Thanks a lot!

According to Yii docs, if your specify SluggableBehavior's attribute property with an array of model attributes, it will implode (concatenate) them in order to generate uniqueness for the slug. In your case, this implementation perfectly satisfies your desired slug concatenated composition (e.g. First-Article-1);
Internally SluggableBehavior will perform it's generateSlug method to generate unique slug from your attributes composition defined in attribute property. Since generateSlug uses - delimiter by default, it perfectly fits your requirements in order to generate desired url slug.
Take a look into this:
public function behaviors()
{
return [
[
'class' => SluggableBehavior::className(),
'attribute' => ['slug', 'id'],
...
]
];
}
EDIT:
This is your URL Rule: 'article/<slug>' => 'article/view'
and
Generating appropriate link: Url::to(['article', 'slug' => $model->slug . '-' . $model->id])
